ML 3561ND engine fuser. low heat error??????

It's in the onboard computer system itself. This is a pre-set by the company that is designed to force you to service the unit, buy parts, etc., whether you need them or not. It is dirty pool I agree, but unless you know how to get into the machine's maintenance menu to re-set all those factory settings, you are pretty much screwed.

This is a nice printer, and what Samsung has done here is a travesty to our trash problem. It will turn out that it is much cheaper to just buy a new printer and toss the one you have, ergo, you are throwing away a perfectly good working printer all because the greedy foreign corporation knows "Stupid Americans" will buy more and more.

There is a way to get in, but it is VERY hard to do, but you are welcome to try:

You can enter the menu in this way:

Start up the machine with push in the buttons "online" and "cancel"
--You will see the message "Download mode press online key"
Press about 15 times the "menu" key
--You will see the message "Uncheck consumable mode"
Press about 15 times "menu" and 5 times "enter"
--You will see "Press access key"
Press a few enters
Press 3 times "cancel"
Go to the EDC mode
-- you will see "press access key"
Press "cancel"
Go to maintenance and initialize the parts you like to reset.

(sometimes you have to try a few times; don't wait to long between each of the steps)

Your printers are NOT broken. It is all in the design and how the likes of Samsung, Sanyo, Toshiba, etc., have figured out a way to screw Americans over, why, it's the favorite Euro/Asian pastime, see how many times you can get brainless Americans to buy your product over and over and over and over, on and on ad nauseum.

I wish you all much luck!

Now, here is what I did, and I do NOT recommend it:

I went to Comp USA and found the floor model. I wrote down the serial number off the back, went home and called Samsung with that serial number - and I was told "Your printer is still under warranty, we'll send someone to your home to repair or replace" How lovely of them. And replace it they did. Now, I haven't gotten the error message with this one, but if I do, I'll do the same thing again. Screw me once, shame on you, screw me twice . . . . .

If you have annother tonner cartridge, (the old one will do)fix it and see if it works. If not there might be a component faillure related to the Fuser Unit. Also check for any Jam in the Pinions(Sometimes Samsung Laser Displays wrong MSG.)

Turn off printer and check temp of the fuser - if cool replace as is faulty.
